Maine Center for Disease Control and Prevention officials say the virus has been confirmed in a Cumberland County individual and is believed to have been been acquired locally.

State officials say they've confirmed Maine's first human case of West Nile virus in a Cumberland County resident. Maine Center for Disease Control and Prevention officials say the individual, whose identity is not being revealed, began coming down with symptoms on Oct. 1.

Those symptom included fever, encephalitis, meningitis, weakness and double vision. Officials say because the patient had not traveled during the exposure period, it's likely that the mosquito-borne virus was acquired in Maine. The patient is now recovered.

West Nile is transmitted throurgh the bite of an infected mosquito, and can cause serious, and sometimes fatal, illness in humans, large animals and some species of birds.

The virus was found in seven Maine mosquito pools tested in August and September. Five of the pools are in Cumberland County and two in York County.

But until now, no locally-acquired human cases of West Nile have been confirmed in Maine. In August, a Pennsylvania resident vacationing in Maine tested positive for the virus, but officials say the disease in that case was likely contracted out of state.
